Just a little off subject but it reminded me of this. Went to school with this girl that knew Sam Walton. He at one time tried to get her to be one of her fabric buyer but she was happy where she was at. Sam had sent a notice out to all of the stores that the riding mowers were to be sold and gone by a certain date with a paper where the store managers were to sign this was accomplished and mail back. Sam, on heading in to one of his stores decided to take his plane over the store just for the heck. He was surprised to see, what else, a riding mower setting on the roof of the store. Manager got fired. Today, Sam could check out anything on the roof with a easy drone flight.
